To all whom it may concern: I p

Be it known that I, HENRY A. \Vrsn Woon, acitizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Machine for Finishing and Cooling Stereotype Printing-Plates, of which the following is a specification.

This invention relates to the shaving, finishing and cooling of curved stereotype printing platesand the cutting of tails therefrom and it is designed to be embodied in machines particularly to be used in connection with any desired kind of the so-called hand casting boxes.

The principal objects of the invention are i to provide an etlicient, convenient and compact form of run-way for receiving the plates and feeding them forward through the various operating devices; to so construct this run-way that it of itself acts to control the feed of the plates therealong; to provide a simplified and improved arrangement for operating the devices for controlling the movement of the plate through the arch and into the cooling device; to provide an improved tail cutter adapted to cut the tail from the inside so as to leave the plate with the proper bevel thereon and remove a minimum of metal; to provide an improved mechanism for operating the tail cutter in an accurate path; to provide means whereby the severed tail will be prevented from passing along down the run-way with the plate and will be left in a convenient position to be removed from the machine by hand; to provide an improvedconstruction of side shaving tool of such a character as to trim off the sharp edges of the plate which have been a source of trouble heretofore; to provide a constructionsuitable for operation by an electric motor, and automatic controlling connections therefor; to provide means in the cooling mechanism whereby it is adapted to receive a plate by gravity from the inclined run-way and gradually stop its motion; without subjecting it to any sudden shock; to provide automatic means for turning on the cooling fluid by the operation of the plate itself when it moves into position in the cooling ClGVlCG; and to improve the details of construction in many particulars.

Reference is to be had to the accompanymg drawings in which Figure 1 is a side elevation of a machine constructed in accordance with this invention; Fig. 2 is an inclined plan of the same lookmg in the direction of the arrow in Fig. 1 with parts broken away to show interior construction Fig. 3 is a similar view of a portion of one of the run-ways on enlarged scale;

Fig. 4C is a side elevation on enlarged scale of the shaving arch and contiguous parts with parts broken away to show interior construction Fig. 5'is a transverse sectional view on the line 55 of Fig. 4;

Fig. 6 is a similar sectional view on the line 66 of Fig. 4;

Fig. 7 is a longitudinal sectional view on the line 77 of Fig. 6;

Fig. 8 is a sectional view on the line8-8 of Fig. 2;

Fig. 9 is a still further enlarged sectional view of a portion of a plate showing how the tail is cut therefrom;

Fig. 10 is a longitudinal sectional view of one end of a finished plate showing how the edges are finished; and Fig. 11 is a sectional view on the line 1111 of Fig. 2.

These drawings show one form in which the invention can be embodied and in this form the machine is shown as comprising a frame A having at one end thereof a platform B for receiving the cast plates from the hand casting box or other device in which they are made and holding them in convenient position for the removal of the matrix by hand. This platform is shown as level for convenience in receiving and holding the semi-cylindrical plates and as provided with guides or tracks for directing the plates into proper position to enter the inclined runway 0 down which the plates are adapted to move by gravity from the platform. Over the inclined run-way is located a shaving I arch D and at the lower end of it is a coolprovided with a motor F. The motor is supplied with power through any suitable electrical connections. A starting pedal is shown connected with a lever 11. The lever is connected by a'link 12 with a circuit breaker 13 by which the operation of the motor can be controlled.

A spring-pressed rod 14 normally tends to hold the lever down in position to break the circuit so that by stepping on the pedal the circuit can be made and the motor started. When this is down an arm or catch 15 connected with the pedal engages a locking lever or latch 16 and holds the parts in that position until automatically released as will be described hereinafter.

The motor is shown as connected through a flexible diaphragm coupling 17 with a shaft 18 mounted in bearings 19 suitably arranged on the frame work A. The shaft is shown as provided with a thrust collar 20 and with a worm 21 keyed 011 the shaft. This worm engages a worm wheel 22 keyed on a transverse shaft 23 which is provided with a worm 24 meshing with a worm wheel 25 keyed on a shaft 26. This is inclined at the same angle as the run-way and is concentric with the shaving arch D. This shaft carries fixed thereon the usual shaving blade 27.

On the shaft 18 is mounted a spiral gear arranged to mesh with and operate a spiralpinion 31 keyed on a shaft 32. Thus the shaft 32 rotates at a higher speed than the shaft 26. This shaft is mounted concentrically with the shaft 26 and projects into it. centrally into a chamber or gear pit 33 therein. The shaft 32 has a bearing at 34 in the concentric shaft 26. The shaft 32 carries in the gear pit 33 a bevel gear 35 meshing with a bevel gear 36 also in this chamber and mounted on a shaft 37. The latter is carried in a bearing 38 fixed on the shaft 26 at an angle to the axis thereof. The shaft 37 carries on its outer end a rotary cutter or saw 39 which is given a planetary motion and a rapid rotation on its own axis while rotating with the shaving knife 27 about the axis of the shaft 26. It is to be observed that this rotary cutter is located inside the curved stereotype plate when it is in position in the finishing arch for the purpose of being operated upon by the shavingknife therein.

On account of being located in this place it cuts the tail from the plate in the manner indicated in detail in Fig. 9.

The cutter 39 forms a conical surface on the plate governed by the angle of the flat side of the cutter to the axis of the plate and it forms an interior conical surface on the tail of the plate. This reduces to a minimum the amount of metal removed, and makes a bevel on the plate edge, at the proper angle to lit the plate clamps on the printing machine- Carried with the shaving blade 27 are shaving side tools 40 for trimming the sharp edges of the plate at both ends which sometimes injure the hands v of the workmen.

This makes a groove? lower than the type.

plate is forced over and up into the arch this permits the tool on one side to yield.

The shaft 26 is providedat a point, preferably just below the arch, with a three lobe cam 45 in the groove of which runs a stud or roller 46 on one arm of a three-arm cam lever 47. The other two arms of this lever are connected by links 48 with a pair of oseillating members 49 at the sidesof the arch and below the same. Each of these oscillatmg members is provided with a pro ection 52 engz-i'ging a pin 500 on an independently pivoted stop 51. These steps are forced to turn inwardly by springs 50. The oscillating members 49 are adapted to be swung by the operation of the cam to force the stops from position under the arch and later to move so as to allow the springs 50 to force the stops inwardly to stop the plate in proper position to beacted upon by the,

finishing devices which have been described. Also mounted on a longitudinal shaft 53 along one side of the arch are lifting levers 54 normally pressed upwardly intothe position shown in Fig. 5 by the spring 140 on the rod 14 and when the starting lever 11 is moved down to stop the machine the rod 14 on which the spring is located positively pulls these lifting levers 54 downwardly with it into the position shown in Fig. 6. In this position a plurality of movable sections 56 (along one side of the runway C and.

under the arch) are projected out into position to support the plate in line with the run-way. This is accomplished by pivoting these sections by means of arms 57 to the lifting levers and by supporting each section 56 on a horizontal ledge 58. A comparison of Figs. 5 and 6 will show clearly how these sections are forced outwardly into position to receive the plate when the lifting levers are pulled down. At this time the cam lever 47 has acted to swing the stops 51 outwardly and hasbrought projections 59 to the level of a fixed ledge 60 on the bottom of the shaving arch and the movable sections 56 in their lowermost position for receiving an outgoing plate. These parts support the plate and constitute a partof the run-way and when tne machine is started the spring 140 forces the lifting levers up again into the position shown in Fig. 5, moves a new plate up into its seat in the arch, and holds it there where it is ready to be actedupon by the rotary finishing device. I The sections 56 and projections 59 receive the plate as it comes into the arch and support it when it is stopped by the stops 51. Then the projections 59 on one side act to lift one edge of the plate to thelevel of the fixed ledge 60. (Fig. 6). Then the lifting levers 54- take the other edge of the plate off the section 56, move it up into the arch and force it over on the ledge 60. '1 (Fig. When the cycle of operations is repeated, of course,

the movable sections 56 and 59 are again brought into alinement with the rest of the run-way and the stops 51' which before projected inwardly are forced back out of the way. Thus each plate is allowed to slide down the run-way ust after finishing devices lea-velt.

It has been stated that the leverll is provided with a hook or latch 15 on the end thereof which engages with a spring-seated locking lever 16 pivoted on the frame so that the plate will remain seated in the arch untilreleased by the action of the three-arm cam lever i? as has beenexplained. When this occurs an extended lobe ofthe cam causes the levers? to swing around to a position in which a" projection 68 thereon engages with a projection Get on the iockinglever 16 forcing it to swingoutwardly at the bottom about its pivot and releasing thestarting pedal so asto allow the spring 14: to force stop is provided consisting of a projection 68 extending up from the upper part of the frame and provided with a cross bar 69 of proper length to engage the inside of the concave conicalend surface of the tail which is formed by the gate in casting. This stops the tail without interfering with the plate itself or the next plate, and leaves the tail where it can be removed from the machine by hand. i I

The cooling device isshown in the form of a concave trough 70 forming at one side a continuation of the inclined run-way'C. The curve of this trough is described from a horizontal axis above the plate at right angles to the path. The trough has on its interior surface and parallel therewith tracks 67 forming prolongations of the inclined run-wa y C. The object of this is to choc-l the movement ofthe-plate when delivered from the shaving arch to the-cooling the rotary trough. Each track is shown as having a notch (36 i for allowing drainage therethrough.

An additional stopping means also is provided. pivotally mounted spring seated stop plate 71 fixed to an oscillatable shaft 81 above the delivery endof the cooling trough. Mow able with this shaft and pivoted on the same .aXis as the plate is an arm 72 with which is pivotally connected a reciproca ble rod 73 having a spring 74: for forcing it up and thus yieldingly holding the stop in projected positionready to receive the impact of a plate. One of the spring rods 73 is provided with a water valve toe piece 75 for opening and clos- This is shown in the form of aing avalve 76 in a water supply pipe 77.

This is suitably connected with a hollow semicylindrical chamber 7 8 placed in the cooling, trough parallel with the path of the plate.

The top ofthis chamber is perforated throughout its length to permit the escape of-the water in a spray against the entire inside surface of thesemi-cylindrical plate. Theztroughis also provided with a partition or closure 79 so placed as to preventthc spray from escaping from the end of the plate toward the arch. The cooling trough is drained by means of a pipe 80 at the lowest point thereof. a

Alsoswinging witlithe shaft 81 are a pair of arms 82. Each of these arms assisted by the plate 71 supports shafts 83 each having slidably mounted thereon a grooved roll 8t normally forced inwardly by springs 85.

When a plate first comes into position to operate the stop plate its upper part engages the rolls and as it slides into a more nearly horizontal position it necessarily forces the rolls apart. The resistance of the springs obviously tends to stop this action thus assisting in bringing the plate to rest.

Theoperation of the various parts of the machine is as follows :--A plate as shown in dotted lines in Fig. 1, is placed on the platformd and moved over by hand onto the inclined runway. The operator then steps on the treadle 10 to start the machine.

The locking lever or latch 16 then automati cally holds the lever 11 in the ope a ting posi tion. When the plate has slid down the runway into the arch D the cams operate and cause the plate to be clamped m the arch by .the movement of the lifting levers 5%. The

the lockinglever 1.6 out ofcngagement with wh en its extreme edge engages the stop plate 71 the water is turned on and the plate cooled.
